Go ahead and break it. You should be replacing the gate valve anyhow. You should only have a proper seacock with a lever actuated ball valve on any fitting below the maximum heeled waterline. And if you are sailing in salt water, the brass gate valve will corrode and freeze up in a surprisingly short time. You should use only bronze or marlon for the valve.
So buy a 3/4" Groco bronze ball valve ($31.99 at West Marine - probably less elsewhere) and a new hose barb and sleep better knowing you've improved the boat.

I want to replace the hose barb with another one, but can't unscrew it from the thru hull valve. Teflon tape shows on the plastic threads of the barb so I expected it would be an easy job to unscrew it, but so far I can't move it. Tried a heat gun on low heat but didn't help. Any ideas what to try? - obviously I don't want to break the plastic fitting and end up with the threaded portion stuck in the gate valve.
